I am using a 15" MacBook Pro Early 2008 2.4ghz and I am experiencing very frustrating issues.
I was just browsing the web and suddenly the keyboard and trackpad died. I was not able to turn on the backlit lights nor was I able to see the green lightning circle when activation caps lock. Only the power button worked…
So I restarted and almost everything seems to be fine..almost: my trackpad won't recognize any 3 and 4 finger swipes. I already tried reenabling it in System Preferences but still no luck. It will probably work again when I restart the computer again but it still is a problem.

Also, I noticed that my MacBook Pro is giving me electric shocks while resting my hand on it! It sometimes also happens when I just type something.
This is really worrying me and it really hurts. It started happening when I went to an Asian country. Never happened before when I was in Europe. I hope it will stop when I am back but you never know..

Oh and before I forget. It happened before that when I touched the trackpad, it instantly gave me a shock and the keyboard and trackpad were dead...

    This is probably all related. You are experiencing a potentially life threatening problem with the grounding and or earth-neutral bond in the facility where you are using the Mac.

    Are you using a grounded outlet with a grounded cord?

    Carefully inspect your battery. Sometimes trackpad and keyboard problems can be caused by a defective battery that is swollen or otherwise deformed. The deformation puts upward pressure on the underside of the trackpad and takes it down; the keyboard can go with it..

    401 cycles is remarkable. However, as long as the battery is not deformed and the health is over ~70 percent and you get modest charge life from it, there is no reason to rush for a new battery. You can use the iStatPro Dashboard widget to monitor battery health:
